put 2.02 s on as is. 2.08 wont work with low lift cam, and low compression ratio.2.08 on that combo will loose lots of bottom end torque...port will stall...to effectively use 2.08 and gain any benefit...you would need to increase port volume from intake port opening down...including unshrouding below valve,narrowing guide....blending chamber floor...increasing static compression ratio...and adding .100 lift to cam....change rocker arm ratio...then once you have the bigger intake charge rammed on top of the piston you got to get the exhaust out of there quicker also...so more work on exhaust port....plus you would need to do some work on intake manifold to make that intake volume larger....lots of work for very little return.....an effective combination that includes all areas must be considered.....better and or bigger carb...bigger exhaust tube primary diameter..looser stall TC,more gear ratio...with no other changes other than swapping on the 2.02s i think you will have a quicker 60 foot time...better mid range....possibly 300-400 more rpm on top end.
